Hmmm, I believe it's static, but how can I tell under AIX?
If I do a 'file' on libstdc++ it replies with the same thing
that it does for libdl.
boreas::/boreas/dlopen-gcc (62)% file /usr/local/lib/libstdc++.a.2.10.0
/usr/local/lib/libstdc++.a.2.10.0:      archive (big format)
boreas::/boreas/dlopen-gcc (63)% file /usr/ccs/lib/libdl.a
/usr/ccs/lib/libdl.a:   archive (big format)

I have an example here with verbose gcc/g++ linking commands.  I don't
see
much that is different, nothing suspicious anyway.  Perhaps what I'm
using
just happens to work in C but is technically incorrect.  Here is the
source, Makefile and the results.  I'm using gcc 2.95.2 downloaded as a
binary from Bull (an AIX freeware site).

Thanks,

Robert
